Water Bugs

Water bug is another name for the common household pest, the cockroach. These insects can grow as large as an inch and a half in length and are typically dark brown or black. Water bugs have hard, chitinous bodies with six legs and long antennae. Not only are these insects found under appliances and in cracks and crevices, but they also are very good climbers and can be found on top of cupboards and in ventilation ducts.

Water Bug Nests

These insects are drawn to cool, dark places to build their nests; most homes provide an abundance of locations that meet these needs. Interior walls, heating ducts, baseboards, cupboards and other dark, dusty areas are prime locations for water bug nests. Water bugs can travel inside walls, chewing their way through them if necessary, to build nests. Because water bugs can travel through the plenty of avenues within the walls of your home, they are not seen frequently during the day. They stay in their nests during the day, leaving at night in search of food and water.


Eradicate Water Bug Nests

Water bugs are extremely hardy insects and the skill and supplies of a professional exterminator generally are required to completely rid your house of an infestation. Commercial insecticides, sprays and dusts from the grocery store may be effective in killing a few insects but, chances are, many more are lurking inside the walls of your home where you cannot reach them. Bait traps may help to eradicate water bug nests, because these traps typically utilize a slow-acting insecticide that, once it is carried back to the nest, will kill an entire colony.

Prevent Water Bugs from Building Nests

Eliminate a potential food supply to prevent water bugs from building nests. Water bugs feed on any food source available, so keep all food in tightly-sealed containers and store them in the cupboard or pantry. Clean up spills quickly and do not allow empty boxes and containers to accumulate. Sprinkle boric acid under your cupboards and appliances to kill any water bugs that come into contact with it; sprinkle natural substances like mint, garlic and cucumber peels around windows, doors and cracks where water bugs might enter your home.
